[Asia Economy Reporter Kim Jong-hwa] Noroo Paint has launched 'Cupid Master,' the industry's first multifunctional water-based paint that prevents exterior wall aging. In addition, it has filed a patent application for 'Water-based paint for preventing neutralization of concrete structures and its manufacturing method.' Let's take a look at the special technology of Cupid Master, which extends the lifespan of buildings with its outstanding functions.

Paint that Enhances the Value of Buildings

Typical reinforced concrete buildings are highly durable structures that can last over 100 years. However, this applies only when the concrete maintains its original strong alkalinity. When rainwater and other elements penetrate, the concrete becomes neutralized, causing rust on the rebar. The rusted rebar expands in volume, leading to structural changes and causing cracks. These cracks can eventually result in partial collapse or damage.

Prevent Concrete Aging with Three Combined Functions

This product not only meets the KS Grade 1 standard but also adds excellent features such as water repellency, elasticity, high weather resistance, wash resistance, and alkali resistance, thereby extending the building's lifespan and increasing its value. The technology of Cupid Master, currently under patent application, simultaneously achieves dense water repellency and elasticity, requiring advanced expertise.

The resin research team at Noroo Paint began developing the resin to realize this technology. Cupid Master is made of 100% acrylic emulsion, maximizing weather resistance while keeping the product price stable through intense research and repeated experiments. It demonstrates performance superior to existing coatings with more than 1.5 times longer accelerated weather resistance test results.

The hard and strong coating film has excellent surface water repellency that prevents moisture penetration and good elasticity that resists fine cracks. It also protects concrete and rebar. Thanks to this, it can prevent the neutralization of concrete.

First Domestic Product Expected to Gain Favor in Apartment New Construction and Repainting Markets

Cupid Master is the first domestic product clearly differentiated from the most commonly used exterior water-based paints and is expected to stand out in the apartment new construction and repainting markets. Concrete multi-complex buildings such as apartments and villas are repainted every 5 to 7 years, but Cupid Master can extend this interval, reducing building maintenance costs.

With patented functions added at a price comparable to general exterior water-based paints, it is the optimal product for consumers who need to make rational choices. As government policies are also expected to move toward strengthening building durability, product demand is anticipated to increase further.

A Noroo Paint official said, "Due to the surge in demand for apartment exterior painting, we have conducted research to enhance functionality, resulting in the industry's first multifunctional product launch. Currently, the exterior water-based paint market has reached a quality plateau, with competition focused mainly on color design. By launching Cupid Master, Noroo Paint has gained a distinctive advantage."
